5th and 7th mag are glowing in a blue-golden light. They can be separated in
small scopes (two inch should be sufficient) when a high magnification is used.

of our Local Group of galaxies.
After our own galaxy and the Andromeda Galaxy,
M31 it is the third largest in the

M33 is a good test. Because it is so
faint against the background sky looking with binoculars is best in a very dark
night. For detailed informations see the Messier database.
